Master Bond Polymer System EP19HTFL is a storage stable one component liquid epoxy resin system for durable, high performance adhesive/sealants, impregnants and liners. It is a one part, non mix system with "unlimited" working life at room temperature as it cures readily only at elevated temperatures to a tough, strong and chemically resistant thermoset plastic. Low viscosity facilitates handling at ambient temperatures and is particularly desirable for impregnation applications. As Master Bond Polymer System EP19HTFL is 100% reactive and does not contain any solvents or diluents and shrinkage upon cure in minimal. Recommended cure conditions are 1-2 hours at 300° (150°C), less at higher temperatures with the minimum cure temperature being 250°F. The cured material has high physical strength properties (tensile strength more than 8,000 psi), is thermally stable (heat deflection temperature more than 270°F) and has superior electrical insulation properties (volume resistivity greater than 10¹⁵ ohm cm) as well as remarkably good chemical resistant properties.

Master Bond Polymer System EP19HTFL is widely used in the mechanical and in the electrical/electronic industries as an adhesive/sealant, impregnant for porous metals and nonmetals and as a high strength, chemically resistant liner. The Master Bond Polymer System EP19HTFL can be used over the remarkably wide temperature range of -60°F to +350°F. The Master Bond Polymer System EP19HTFL has a shelf life of 4 months when stored at 75°F. The shelf life can be extended 6 months by storage at 40°F to 50°F.
